Okay, so i just bought 3 lb package of Scotts Select Plant Food: All Purpose. It's NPK value is 10-10-10. I need to seperate each kind of pellet that is in it. On the "ingredient" list of chemicals on the back, Nitrogen is Ammoniacal and Urea Nitrogen; Phosphorus is Available Phosphate; Potassium is Soluble Potash. There are 3 different colored pellets in the fertilizer. One kind is white (I believe this is the nitrogen), one kind looks like a rock and is dark/light greyish, and the last kind is rock-like and seems to be peach-pinkish. If anyone can enlighten me as to which pellet is which nutrient, I would be very thankful!

I know that one of our planets travels on a course that doesn't fall into the same plain as the others. Could every planet travel in a different plain? Why or why not?

We have 7 wild cats of various ages that live around our house, we feed them on our back porch and generally leave the garage door open for them to stay in when it's cold. This became problematic when a raccoon and opossum began to feed on the left over food on the porch and made themselves at home in the garage. This is dangerous because we don't want to be attacked, and don't want our cats being attacked. How do we get rid of the raccoon and opossum with our getting rid of the cats?
